Abstract The aim of this thesis is to develop and establish the identification,purity assessment and library match using advanced detection techniques and software; DAD with Empower® 2 Software, prior to simultaneous determination of drugs, preservatives and their corresponding degradation products in their pharmaceutical preparations. In addition, the use of mathematical transformation of the collected UV absorption data points of the separated peaks into their corresponding Log A and Relative absorbance(RA) versus wavelengths plots were applied as tool for identification and purity testing. |
